ok read down at the bottom and you can see whats in my car. yeah i finally got a fuel pressure regulator. it is a used blue billet paxton adjustible regulator for $35. i know how to put it on my fuel rail but i dont know how to adjust it. i know how to adjust the set screw on top but do i adjust the pressure with the vaccum line on or off and i know it should be set at approx 40lbs. i have also purchased 24lb injectors and a 70mm mass air but i wont have them till the end of april so i just want to get this regulator on with my stock 19lb injectors.

i know on stock to slightly modified cars the fuel pressure should be at 38-40 without the vaccum line hooked up when you hook up the line it should drop to about 32-35psi, you might need more fuel pressure than that though because of your mods.

I say set it to 38psi vac off like mentioned above, make sure you tighten the 9/16" nut on top after you are done adjusting. Turn it a little then hit the throttle and see where the pressure settles, then lock the nut down. Are you running a FMU?

The adjustable regulator will only give you more fuel at WOT, the stock EEC will adjust the pulse width of the injector to make the A/F ratio what it needs to be, the only way to get more fuel down low is to increase the injector size.
